My Whirlwind doesn't even shoot the ball around the guide to the third flipper. It usually doinks on a post or whatever and misses the ramp or guide 9 out of ten times. I have a feeling most playfield swaps need to be tweeked quite a bit to get right for each differenct game. I am assuming the best bet is to trace the holes on your old playfield and match to the new one? I think the biggest problem is alot of guys(myself included) are just getting into swapping and all these little variations can cause things to be ruined if not handled correctly. I appreciate seshpilots posts as it makes me aware of the issues. I am still waiting for my playfield luckily and by the time I get ready to start mine hopefully some more experienced guys post more tidbits to make the transition smoother. To be honest you'd think that one playfield for the dimples and holes would be enough. It seems you are inviting more problems by using multiple playfields and putting them together. Correct me if I am wrong.
